I show this professor mccurdy here covering some of the markings of the skull so first off we've got these sutures right this would be the coronal suture this would be the squamous suture this inverted V suture here that would be the lambdoid suture this would be the saddle suture here sutures as umino or joints that hold bones of the skull together let's see let's start with markings we'll start with temporal bone right this flat part here is known as the temporal swing squeemish this part that juts out here that is the cyclomatic process it's so named because it touches the zygomatic bone this hole here is the external auditory meatus immunise is a tube-like opening this is one on the outside that is for the ear Hintz external auditory this rounded process is the mastoid process mastoid refers to the shape of a breast and hence it is rounded and this poignant process here is the styloid process right styloid is a pointer right inside the cranium we can see some more parts of the temporal bone we can see the Petrus portion which a pointer visual that's this Ridge right here and reach here that is the internal auditory meatus there is our Simona however I believe we will do the frame and are related to the temporal bone in another video moving on to the occipital bone right you see this bony protrusion right here that is the external occipital protuberance right there's also an internal occipital protuberance over your structures list this larger hole right here this is only framing I'm gonna do in this video this is the foramen magnum which literally means the large hole right at SRI spinal cord goes and on either side we have the two occipital condyles which articulate with the the atlas right the first cervical vertebra let's see the kreidel bones do not have much of markings frontal bones right frontal bones have a you know or the superior border of the orbits rate the orbit is the eye socket let's see we have the super orbital margin which is the superior border of the orbit super orbital refers the fact that it's above the orbit and some skulls will have supraorbital foramen ah others will have super orbital notches or a it just kind of depends on whether or not the bone closed this rate that would be these things here as far as the ethmoid bone all right you can see portions the ethmoid bone here in the nasal cavity you can see the perpendicular plate which goes up and down and separates the nasal cavity into two halves it's part of the nasal septum and I don't know if I'm gonna be able to point to it but that that thing hanging down right there that is the middle nasal Concha right you actually have three nasal caca you can see the inferior nasal Concha that would be the only bone in the day I forgot at my last video that's a separate bone but the middle nasal conga they are part of the ethmoid bone you cannot see the superior nasal Concha on this this this model here you can see portions of the ethmoid bone here that stick up into the skull this pointy bit here that is the crista galli or your first tooth that they know on top of our roosters head also this flat part with the holes in it that is the cribriform plate those holes are olfactory foramina which contain the olfactory nerves moving on to the sphenoid bone right sphenoid bone has two wings right so this right here and this over here would be the lesser wing right and this portion down here in the middle cranial fossa that would be the greater wing I'm gonna do a separate video on the fer Aminah but this portion right here that is the the sella turcica which apparently a pers - a turkish saddle and the fossa in the middle of the solar so good that's the hypothesis just a little lap moving on to some of the facial bones you'll notice that is there's this like sort of point - but to read here on the lacrimal bone there is the lacrimal fossa right that's for your names with lacrimal ducts which trained your tears on the maxilla I know I said I was going to do this a different video for all the fur Aminah but I'm go ahead go ahead and mention the infraorbital for animate here in here and the incisive foramina which is next to your incisors this mandible doesn't really want to move out of the way but that's right there it would be the insights of perimeter this structure here that is the Palatine process right is process and sticks off your maxilla it forms part of the palate and they're also listed in your sheets it's not necessarily part by the maxillary bone but maxillary bone forms portion of its border you have the new cavity on the mandible itself you have two mental foramen ah you also have two sorry I had that part up alright here we have the Ramos rate the angle and the body right there are two processes on mandible this one that forms part of the joint that in the posterior one that is the condylar process also known as the mandibular condyle and right next to it is the coronoid process right you might have recognized the coronoid processes that are several in the body take it their name because they are pointing like a crown finally on the psychomat ik bone right this is called the temporal process because it articulates with the tipple bone right a portion of the bone is the zygomatic process and together the temporal process and zygomatic process they make up the zygomatic arch I'm sure the best way to show you that yeah so those are the markings on the skull and I omitted most of the Femina at least the larger foraminal inside the cranium first ever video right thanks
